IEhe machine-illustratediis .provided 1with a the usual form of tool carrier or standard 20 mounted at the side of the truck, herein upon the standard-carrying bracket 21' (Figs. 4: andb) the latter being: split and adapted to be adjustably positioned and clamped upon the trunnion bar 22 at either end, of the truck.

Any desiredtform or construction of chan" neling tool or motor may be employed, but herein there is illustrated a common form of compressed air channeling engine 23hav ing rigidly secured to the cylinder thereof cross-head guides 24, the tivo' constituting a sliding frame adjustable lengthu' i'se I the 5 standard as iscustomary, through the medium of the feed screw 25. n

Any suitable means may be employed-to turnthe feed screw, buther'ein there are provided loose upon the truck driving shaft 17 gears 26 and 27 (Fig. 4), these being driven in opposite directions by engagement With gears 7 and 8, respectively: The gears 26 and 27 may be scparately'clutched to or unclutched from a sleeve onwhich the beveled gear 28 is fixed, which gear meshes With a beveled gear 29, the'latter having suitable connections to turn thefeed screw.

Either one of the gears 26 or 27, which, it

' Will 'beobserved, are continuously rotated in opposite directio'ns,:may be clutched to the sleeve 30 of'tlie beveled gear,- sliding clutch 1 members 3l and 32 being provided for'that purpose. The clutch members are movedsimultaneously'by means of the sliding rod 33 and the lever iaf When the lever and rod are thrown to one position; the gear-26 is clutched to the sleeve 30, turning the feed gear 29 in one direction. .Vhen lever and rod are moved to the opposite extreme, the gear 26 1s unclutched from the:sl'eeve= and tl1e gear 27 clutched thereto rotating the gear 29111 the OPPOSltQ'CllI'QCClOIl." In an" intermediate position, such as 1s shown in:

Fig. 4,-botl i gearsare unclutched and the feed'screw remains fixed. The beveledgear 29'is herein iournaled upon a bracket or 'boX 35- which latter. is adjustably clamped in: suitable arc-shaped Ways (see Fig. l), so i that it maybe placed in operative'rela'tion to the beveled gear 28 .in all positions of the standard. The beveled gear 29 hassecured I thereto'for rotation therewith the sprocket Wheel 36 over Whichpasses the feed sprocketchain 37.

ing movement thereof when required for corner cutting. withoutinterference with the tool feeding mechanism, thefeed-sprocket' chain is caused to pass over suitable-guiding-sprocket wheels 38 and 39 and thence" to a sprocket wheel lO, the latter being arranged co-axially 'with the standard as will I be more fully referred to. The guiding I sprocket wheels 38#and 39 are carried by'a To permit the various angular adjustl ments of the standard, as Well as the swing- I bracket or frame 41 which is adjustably clamped to the trunnion bar 22 so that its position may be adjusted and the proper tension and direction of the feeding chain at all times maintained. The sprocket wheel (Fig. 5) is mounted upon the sleeve 4.2 a

with its-companion sprocket wheel 43, the sleeve being jou'rnaled upon the axial member or bracerod'td. The sprocket wheel 43 engages and drives the second feed chain 45, r

the latter passing up and over the sprocket wheel 46. The sprocket wheel 46. isv connected 'to'drive the beveled gears 47 and 48" and the .feed'screw 25.

kept under suitable tension by means of the idle sprocket Wheel 49 carried by the arm 50 adjustably secured to the standard.

The chain 45 is j From the described connections, it'will be 1 seen that the feed s'crewmay be turned at will in either direction irrespective of the direction of movement of the truck IOI" whether the truck 'isat rest or in motion. It will also be seen that the bracket 41 may be adjusted to correspond to any inclined adjustment of the standard and that, the sprocket wheels 40 andl3 being co-axial with the standard, the feed is effective'irrespective -of Whether the standard is fixed or undergoing the swinging movement hereinafter referred to. i T

Referring again to the tooleactuating-engine 23, the piston rod 51 thereof is secured to across-head 52, the latter adapted to slide in the cross-head guides 24 and having attached thereto the tool or tools 53 constituting'the channeling gang.

The described form of hanneler maybe employed in'the usual Way in cutting anordinary channel groove. That is tosay, the

standard may be clamped in fixedpositionon the truck (as, for example, the position;

shown in Fig. 1, but Without the'connection's to the rails therein=shown),'one or more of quarry in some suchposition'as is represent- 1 ed in Fig. 2 and there is then connectedto.

The q upper part' ofthe standard; howeven being held back relatively" to; the'pivotahpoint; causes the tool gang rto-swinglor move from the 'posit-ionishown*inFigul to that shown inFig. 2,- the cutting edges'describing a path which may be'similar ztoxthat indicated in Fig 2 and is suitable. for cutting under the overhanging side wall of the quarry. .The' top of the standa rdswings back during this movement to the inclined position :shown in: Fig. .2. so'thatthe truck is perm'ittedto move 1,; close in under the overhanging side, wall-1 and secure the full benefit of 'the forward reach of the gang.

to .draw the tapered'walls of'the sleeve 69 tightly in against the bushing 72, the latter being fixed in the standard. The sleeve 69 therefore constitutes a pivotal support upon which the cutting appliances, including the standard and the tool gang carried thereby, are pivoted.

The rear end of the axial bracerod 44: (see Figs. 4 and 5) is adjustably secured to-the fixed frame brace 7 5 by the following means: on the end of the axial brace rod there is clamped'by means of the clamping bolt 76 the horizontally split clamphanger 7 7 The clamp hanger is transversely perforated to receive the clamping bolt 78, which has threaded engagement with the clamping nut 79, the latter having the shoe SO fitting the arc-shaped slot 81 in the frame brace 75. The slot 81 is curved about theaxis of the trunnion shaft 22 as a center so that by means of the clamping bolt 7 8 and the nut 79the rear of the axial brace rod may be adjusted and held fixed in any desired angular position-to accommodate the tipped position of the standard. Between the clamp hanger 77, which maybe adjustably clamped in diflierent positions on the brace rod 44, and the adjustable clamp collar 82 there is held fixedthe back brace. swivel block 83 Consisting of a sleeve having an upwardly directed lug on which'the lower end of the brace rod 84: is swiveled. The brace rod 8% is telescopically adjustable and has jointed connection at its upper end to the standard 20. I

It will be seen that the standard can be tippedback to any inclined position and the machine can be used to'cut a channel groove with the standard held fixed in such position 1 .Or while the-same is caused to oscillate, the power-actuated feed of the tool being maintained both during the swinging movement of the tool and the fixed position of the standard irrespective of the angle to'which the latter may be inclined. It will be obvious that the invention herein as to its broad features is not limited to its embodiment in track channelers or in channeling machines of any specific type, nor is it limited for all .purposes to the connection of the tool to a point extraneous to the truck or other movable support employed.

l Vhile I have herein shown and described for purposes of illustration one specificembodiment of the invention, it is to be understood that the latter is not limited to the detailsof construction herein shown nor to the application of the invention herein illustrated nor to the specific form of machine .to which the same is shown as applied, but that extensive deviations may be made therefrom without departing from the spirit of the invention.
